In The Breakfast Club Allison (the Basket Case) is seen as weird and does not fit in with the others. Throughout her time in detention she learns that she is not the only one in the group that feels like an outcast. She discovers that her unhappiness in her home life is not her fault and that everyone has problems at home. While at detention Allison finds to accept herself, she also learns to accept her classmates. For example, she sees that while Claire may appear stuck up and perfect but really she is unhappy as well.

Allison stands at 5'5, and has a quite slim figure. Dark brown hair with a black hue sometimes, it tends to cover her face a lot. Her skin is pale and with a very light dusting of freckles. Her face is pretty sorrowful a lot. However, after a makeover from Claire, it reveals that she is secretly beautiful, and Andrew begins to show signs of attraction, and so does Brian.
